FABRIC-PRINTING MACHINE.

Specification of Letters Patent.

Application filed September 3, 1909.

To all whom it may concern:

Be it known that I, ERNEST Bon'rnnrs, engineer-chemist, a citizen of theFrench Itepublic, residing at Ivanovo-Vosnessensk, Russia, have inventeda new and useful Fabric-Printing Machine, of which the following is aspecification.

My invention relates to machines or apparatus for printing fabrics andmore especially to machines adapted to print only on the threadsappearing on a fabric in re lief. To this end, I so construct mymachine, that one of the printing elements is movably arranged, and Iprovide adjusting means, whereby the movable printing ele ment is heldat a certain distance from the other printing element, which distance isdetermined in each case by the height to which the threads to be printedon project from the general plane of the fabric.

In order to make my invention better understood, I have illustrated thesame in the accompanying drawings in a more or less diagrammatic manner,Figure 1 showing one way of movably arranging one of the printingelements, Fig. 2 showing another way, Fig. 2 being a section along line]lri in Fig. 2. Figs. 3, 3 ant 3* illustrate a further modification.Figs. 4, 4 and 4* illustrate an arrangement similar to Fig. 1, incombination with means to permit printing from a pattern. Figs. 5 and 6are details illustrating further means for keeping the printing elementsseparated at a certain distance.

Similar reference letters denote similar parts in all the differentviews.

Referring first to Fig. 1, the printing elements comprise the impressioncylinder a and the printing cylinder 5, adapted to rotate around theiraxes. The smoothly polished impression cylinder a rotates in a fixedposition and is journaled in stationary standards t. inder b is movable.To this end the cylinder Z) is journaled in a pair of lever arms, whichcan be adjusted about a pivot 0 so that the cylinder 5 can be movedtoward or away from the impression cylinder a. By means ofa screwspindle "0 the distance, at which the movable printing cylinder 1) isheld away from the stationary impression cvlinder, can be exactlydetermined. This distance corresponds to the height to which the threadsto be printed on project from the general plane of the fabric T which ispassed over a guide roll 1' and then around the impression cylinder a inthe direction of The engraved printing cy1- l the arrow shown in Fig. 1.In order to firmly hold the movable printing cylinder against theimpression cylinder, a spring 0, engaging the lever arms t, or a weightI may be provided, as clearly shown in Fig. 1. For practical purposesthe printing cylinder I) should be adjustably mounted on the lever armst to permit the cylinder Z) to be raised or lowered so as to place it atexactly the b'tllllt) height as the impression cylinder a.

The screw spindle v prevents the cylinder 1) from approaching theimpression cylinder o farther than to a certain extent, while permittingit to move away from the impression cylinder, in case the fabric passingbetween the two cylinders is thicker at placesthan the distance at whichthe two cylinders have been ad usted.

As indicated by the line fg in Fi 1,

the journal bearings of the printing cylinder 5 may be freely mounted onan inclined plane, so that the cylinder I) will be moved toward theimpression cylinder (2 by its own weight. Instead of suspending thelever arms t and t from a pivot, as shown in Fig. 1, they may besupported by the axes of the two cylinders by means of projections t iprovided on the lever arms. This embodiment of my invention is shown inFi 5. It

is obvious that, instead of the printing cy1-.

inder Z), the impression cylinder a can be 'movably mounted, the effectbeing in both cases the same.

The guide roll 1* is preferably covered with felt, to thereby secure abetter grip of the roll on the fabric, thus holding it under the desiredtension and causing the threads to be printed on to better pro ect fromthe fabric. Below the engraved printing cylinder, as usually, a scraper1" is provided, and in contact with the printing cylinder an inkingroller 6 is mounted in such a way as to take up and transmit the colorfrom an ink well (Z to the printing cylinder 5.

In the embodiment shown in Fig. 2, the printing cylinder 1) is journaledin bearings, adjustably carried by a pair of rods \I. These rods arepivoted with their lower ends at 0, so that by their own weight they aremoved toward the impression cylinder a. In this construction thedistance, at which the two cylinders are held apart, is also determinedby a screw spindle e, which bears against an abutment not shown. Meanssuch as a spring or a weight to hold the printing cylinder Z) againstthe impression cylinder (1 can in this construction be dislooselymounted thereon, which rings are held in position by stops n and wherebythe distance between the two cylinders is de termined. The rings is,being loosely mounted on cylinder a may be easily exchanged to providefor different distances according to the thickness of the fabric to beprinted on. This construction is especially adapted for cylinders whichare not truly finished.

Fig. 4 shows an embodiment of my invention, in which the cylinders a andZ) are I mounted similarly as shown in Fig. 1, but

in combination with means, whereby a design can be produced from apattern which is larger than the circumference of the cylinders. To thisend a device is used which permits the fabric to be printed onintermittently only. To this end an endless chain g which passes betweenthe guide rollers r T is driven at suitable speed. According to thelonger or shorter pattern, which is used, the chain may be shortened orlengthened between the points 2 and 2. To any link of the chain may beattached a pin a, having pivoted to it a .disk 2', as shown in Fig. 4When the said disk 2' passes the plate P, it will depress the lever I,moving it to the position I shown by the broken lines in Fig. 4. Indoing so, the disk '5 swings about its pivot pin u. The plate P can beadjusted nearer to or farther from the chain g, as desired, by means ofthe screw spindles o, whereby the required distance is obtained, and theprinting cylinder Z) is then moved so far from the impression cylinder athat the relief portions of the fabric are not printed on. In thisposition, the printing cylinder rotates idly. The teeth of theintermeshing gears at the ends of the two cylinders (shown in Fig. 3)are made sufiiciently long to prevent the gears from becomingdisengaged. A screw y at the other end of the lever I permits thepositioning of any other pair of cylinders a, b of another diameter.During this movement the lever I of itself falls into the position I, asindicated by the broken lines in Fig. 4, since the longer arm of thelever I is heavier than'its shorter arm 05. Hence, the latter is movedto the position w, where it is arrested by the stop 2. The lever I isthus held in tion in contact with the impression cylinder (4 by thespring 0. The system of levers is equally provided on both sides of theendless chain g, which is further guided by the ;large guiding wheelsIt, It. The pins u and a are carried by forks h, g, which are secured tothe endless chain g. A series of forks with pins can be provided, andthe pins are arranged in such a manner that each pin divides thedistance between themembers it and g of the fork into sections ofdifferent lengths, whereby the distances required for the printing inaccordance with the pattern are very exactly obtained. Either one, ormore pairs of printing elements can be used with the endless chain. Fig.4 shows only one pair of printing ele ments, which, as has already beenstated, are arranged as shown in Fig. 1. a is the smooth impressioncylinder, 6 the engraved printing cylinder, carried by the arms t. Bymeans of the screw V the pivot O can be "aised or lowered. c is thespring which tends to move the cylinder Z) toward a. The screw spindle 0determines the distance, at which the cylinder 1) shall be kept awayfrom the cylinder a. The speed at which the cylinders are rotateddepends, of course, on the kind of fabric to beprinted on.

I claim In a fabric printing machine, the combination of an impressioncylinder adapted to rotate in a fixed position, a rotatable printingcylinder adapted to cooperate with said impression cylinder, bearingsfor said printing cylinder, a pair of rods adapted to adjustably supportsaid bearings and pivoted at their lower ends so as to move by their ownweight toward the said impression cylinder, an abutment, a screw spindlein cooperation with said rods and bearing against said abutment fordetermining the distance between the two said cylinders, and means, suchas a screw, for raising and lowering the said rods thereby adjusting therelative cooperative position of the two cylinders.

In testimony whereof, I have signed my name to this specification in thepresence of two subscribing witnesses.
